Pilot Knob
Pilot Knob, the only example of an exposed submarine volcano in Texas, appears today as a prominent hill one mile northwest. It was formed some 80 million years ago on the bottom of a warm, shallow sea which covered much of the continent during the Cretaceous Period. The molten rock which it spewed forth rose to the surface from deep within the earth's crust, following a channel opened by a belt of fractures known as the Balcones Fault zone. Reef organisms were attracted to the irregularity on the sea floor. Seeking food and protection on its slopes, they multiplied rapidly, not unlike coral reefs form now in the south Pacific Ocean. As corals, starfish, oysters and other marine life died, their shells and skeletons were fossilized around the volcano. Outcroppings of the small reefs which they formed can be seen today along the banks of Onion Creek, immediately north of Pilot Knob. As the Cretaceous Sea receded, the volcano was exposed in its entirety. The long weathering to which it was subjected eroded much of the mass, leaving only the central portion or vent. Today, it rises 710 feet above sea level. 180 feet above the surrounding valley. Diameter of its rim is 1.5 miles
As one of the most visible programs of the Texas Historical Commission (THC), historical markers commemorate diverse topics in Texas history, including: the history and architecture of houses, commercial and public buildings, religious congregations, and military sites; events that changed the course of local and state history; and individuals who have made lasting contributions to the state, community organizations, and businesses.
The Texas Rangers, a famous law enforcement agency, were first organized in 1835 to protect settlers from Native American attacks.
European exploration of the region began in the 17th century when Spanish explorers ventured into what is now Travis County. However, it was not until the early 19th century that permanent settlements were established. In 1835, the area became part of the Republic of Texas after gaining independence from Mexico, and the county was officially created in 1840.
Travis County was named after William Barret Travis, a Texas Revolution hero who commanded the Texan forces during the Battle of the Alamo in 1836. Throughout the 19th century, the county experienced significant growth and development, driven by factors such as the arrival of immigrants, the expansion of the railroad, and the establishment of institutions like the University of Texas at Austin in 1883.
During the 20th century, Travis County continued to evolve and modernize. Austin, the county seat and state capital, grew into a vibrant and culturally diverse city, known for its live music scene, technological innovations, and progressive policies. The county became a center for government, education, and business, attracting a wide range of industries and residents.
Today, Travis County is one of the most populous and economically vibrant counties in Texas. It is home to a diverse population and a wide range of cultural, educational, and recreational opportunities. The county's history, coupled with its present-day dynamism, contributes to its unique character and makes it a significant region in the Lone Star State.
